y2038: move itimer reset into itimer.c
Preparing for a change to the itimer internals, stop using the
do_setitimer() symbol and instead use a new higher-level interface.
The do_getitimer()/do_setitimer functions can now be made static,
allowing the compiler to potentially produce better object code.
